1Distribution of correlation dimensions of synchronous 12-lead ECG signals显示文摘Correlation dimensions D2 of the synchronous 12-lead ECG signals have been investigated for the first time by distributed multi-sensor (multi-electrode) technique. The results show that correlation dimension of heart has the distributed characteristics. D2 calculated from different lead ECG signals is not a constant regardless of a healthy person or a coronary heart disease (CHD) patient with sinus rhythm. But with the same lead signal, D2 of CHD patients is evidently smaller than that of a healthy person except I, II, III leads. A healthy person and CHD patient can be identified by D2 statistically and D2 shows the potential application in the diagnosis of the CHD patients.WANG Zhenzhou NING Xinbao ZHANG Yu DU Gonghuan 2000Chinese Science Bulletin2000,45,17:13
2Hydrological and water cycle processes of inland river basins in the arid region of Northwest China显示文摘The increasing shortage in water resources is a key factor affecting sustainable socio-economic development in the arid region of Northwest China(ARNC). Water shortages also affect the stability of the region's oasis ecosystem. This paper summarizes the hydrological processes and water cycle of inland river basins in the ARNC, focusing on the following aspects: the spatial-temporal features of water resources(including air water vapor resources, runoff, and glacial meltwater) and their driving forces; the characteristics of streamflow composition in the inland river basins; the characteristics and main controlling factors of baseflow in the inland rivers; and anticipated future changes in hydrological processes and water resources. The results indicate that:(1) although the runoff in most inland rivers in the ARNC showed a significant increasing trend, both the glaciated area and glacial ice reserves have been reduced in the mountains;(2) snow melt and glacier melt are extremely important hydrological processes in the ARNC, especially in the Kunlun and Tianshan mountains;(3) baseflow in the inland rivers of the ARNC is the result of climate change and human activities, with the main driving factors being the reduction in forest area and the over-exploitation and utilization of groundwater in the river basins; and(4) the contradictions among water resources, ecology and economy will further increase in the future. The findings of this study might also help strengthen the ecological, economic and social sustainable development in the study region.CHEN Yaning LI Baofu FAN Yuting SUN Congjian FANG Gonghuan 2019Journal of Arid Land2019,11,2:12
3Acoustic radiation field of the truncated parametric source generated by a piston radiator:model and experiment显示文摘A theoretical model is presented to describe the parametric acoustic field generated by a piston radiator. In the model, the high-frequency primary wave interaction region that is truncated by a low-pass acoustic filter can be viewed as a cylindrical source within the Rayleigh distance of the piston. When the radius of the piston is much smaller than the length of the parametric region, this model is reduced to the Berketey’s End-Fire Line Army model. Comparison between numerical calculations and experimental measurement show that the generated parametric sound field (especially near the axis) agrees well with the experiment results.ZHAO Xiaoliang,ZHU Zhemin,DU Gonghuan (Institute of Acoustics and State Key Laboratory of Modern Acoustics, Nanjing University Nanjing 210093) TANG Haiqing,LI Shui,MIAO Rongxing (Hangzhou Applied Acoustics Institute Fuyang, Hangzhou 311400) 2001Chinese Journal of Acoustics2001,20,1:8
4Potential risks and challenges of climate change in the arid region of northwestern China显示文摘In the arid region of northwestern China(ARNC),water resources are the most critical factor restricting socioeconomic development and influencing the stability of the area’s ecological systems.The region’s complex water system and unique hydrological cycle show distinctive characteristics.Moreover,the intensified hydrological cycle and extreme climatic and hydrological events resulting from global warming have led to increased uncertainty around water resources as well as heightened conflict between water supply and water demand.All of these factors are exerting growing pressures on the socioeconomic development and vulnerable ecological environment in the region.This research evaluates the impacts of climate change on water resources,hydrological processes,agricultural system,and desert ecosystems in the ARNC,and addresses some associated risks and challenges specific to this area.The temperature is rising at a rate of 0.31C per decade during 1961–2017 and hydrological processes are being significantly influenced by changes in glaciers,snow cover,and precipitation form,especially in the rivers recharged primarily by melt water.Ecosystems are also largely influenced by climate change,with the Normalized Difference Vegetation Index(NDVI)of natural vegetation exhibited an increasing trend prior to 1998,and then reversed in Xinjiang while the Hexi Corridor of Gansu showed the opposite trends.Furthermore,the desert-oasis transition zone showed a reduction in area due to the warming trend and the recent rapid expansion of irrigated area.Both the warming and intensified drought are threatening agriculture security.The present study could shed light on sustainable development in this region under climate change and provides scientific basis to the construction of the“Silk Road Economic Belt”.Yaning Chen Xueqi Zhang Gonghuan Fang Zhi Li Fei Wang Jingxiu Qin Fan Sun 2020Regional Sustainability2020,1,1:6
5中国慢性病的挑战与应对显示文摘中国在短短几十年内,完成了从传染病向慢性病的流行病学模式转变,转变速度远远高于其他许多国家。而行为模式的转变,包括膳食习惯变化、体力活动减少、高水平的男性吸烟率等危险因素是中国疾病模式快速转变的重要原因。其结果是,这些本可避免的慢性病的发病率和死亡率快速上升。引发了医疗卫生服务费用显著上升。目前,中国有1.77亿高血压患者,有3.03亿烟民(占世界烟民的1/3),并有5.3亿人遭受被动吸烟危害。Gonghuan Yang Lingzhi Kong Wenhua Zhao Xia Wan Yi Zhai Lincoln C Chen Jeffrey P Koplan 2008世界临床医学2008,2,6:5

10Water use efficiency data from 2000 to 2019 in measuring progress towards SDGs in Central Asia显示文摘Central Asia,located in the hinterland of the Eurasian continent,is characterized with sparse rainfall,frequent droughts and low water use efficiency.Limited water resources have become a key factor restricting the sustainable development of this region.Accurately assessing the efficiency of water resources utilization is the first step to achieve the UN Sustainable Development Goals(SDGs)in Central Asia.However,since the collapse of the Soviet Union,the evalua-tion of water use efficiency is difficult due to low data availability and poor consistency.To fill this gap,this paper developed a Water Use Efficiency dataset(WUE)based on the Moderate Resolution Imaging Spectroradiometer(MODIS)Gross Primary Production(GPP)data and the MODIS evapotranspiration(ET)data.The WUE dataset ranges from 2000 to 2019 with a spatial resolution of 500 m.The agricultural WUE was then extracted based on the Global map of irrigated areas and MODIS land use map.As a complementary,the water use amount per GDP was estimated for each country.The present dataset could reflect changes in water use efficiency of agriculture and other sectors.Yaning Chen Gonghuan Fang Haichao Hao Xuanxuan Wang 2022Big Earth Data2022,6,1:2
11Climate change in the Tianshan and northern Kunlun Mountains based on GCM simulation ensemble with Bayesian model averaging显示文摘Climate change in mountainous regions has significant impacts on hydrological and ecological systems. This research studied the future temperature, precipitation and snowfall in the 21^(st) century for the Tianshan and northern Kunlun Mountains(TKM) based on the general circulation model(GCM) simulation ensemble from the coupled model intercomparison project phase 5(CMIP5) under the representative concentration pathway(RCP) lower emission scenario RCP4.5 and higher emission scenario RCP8.5 using the Bayesian model averaging(BMA) technique. Results show that(1) BMA significantly outperformed the simple ensemble analysis and BMA mean matches all the three observed climate variables;(2) at the end of the 21^(st) century(2070–2099) under RCP8.5, compared to the control period(1976–2005), annual mean temperature and mean annual precipitation will rise considerably by 4.8°C and 5.2%, respectively, while mean annual snowfall will dramatically decrease by 26.5%;(3) precipitation will increase in the northern Tianshan region while decrease in the Amu Darya Basin. Snowfall will significantly decrease in the western TKM. Mean annual snowfall fraction will also decrease from 0.56 of 1976–2005 to 0.42 of 2070–2099 under RCP8.5; and(4) snowfall shows a high sensitivity to temperature in autumn and spring while a low sensitivity in winter, with the highest sensitivity values occurring at the edge areas of TKM. The projections mean that flood risk will increase and solid water storage will decrease.YANG Jing FANG Gonghuan CHEN Yaning Philippe DE-MAEYER 2017Journal of Arid Land2017,9,4:2
